Newsletter Sponsorships

Buying a placement in someone else's newsletter. For B2B and prosumer products it's often the cleanest creator channel: the writer has already earned the reader's attention, the audience is easy to describe, and every placement can carry its own tracked link.

This reference covers picking newsletters, reading past results before you book again, writing to placement specs, and tracking each send. The deal terms, disclosure rules, and brief elements in this skill's main sections apply here too.

Choosing and vetting newsletters

Judge a newsletter by who reads it and what earlier sponsors got. List size matters least.

• Read three recent issues. Is the content close to your category? Do the other sponsors sell to your buyer? Do readers reply or comment?
• Ask for the audience breakdown: role, seniority, company size, geography. Writers who know their readers can answer quickly.
• Ask for clicks per sponsor placement, as a median across recent sends. Open rates are inflated by Apple Mail Privacy Protection, which has opened mail automatically since 2021, so treat opens as a ceiling.
• Ask how many sponsors renew. Sponsors that book again are the best evidence the list converts. Ask for one to contact.
• Turn the price into a cost per click. Divide the price by the median clicks, then compare it with your best channel's cost per click. The placement has to beat what the same money would buy there.
• Test before buying a bundle. Run one placement, read the result, then negotiate a package with what you learned.

Sponsorship marketplaces (for example Passionfroot, Paved, or beehiiv's ad network) make finding and booking newsletters faster. The vetting questions above still apply.

Read past results before you book again

For any newsletter you've sponsored before, read what each earlier placement did before you write the next one. Past results are the best guide to which angle to run.

Build one row per earlier placement:

Then write a few lines under it:

• Top placement by clicks or revenue. What about its structure is worth repeating?
• Top placement by signup rate. Which hook brought the right readers?
• Near-zero clicks. This usually means the placement didn't go out (the issue slipped, the link broke, the ad was cut). Confirm with the newsletter before you blame the angle.
• Angles run on this list in the last 30 days. Don't repeat them. Readers who saw the angle recently tune it out, and lists with overlapping readers count as the same list.
• The call for this placement: the angle you're choosing and why. If you go against what the data shows, say why.

The angle has to be recorded with each placement for this to work. A click count with no angle attached tells you nothing about what to write next.

Placement specs

These are one program's specs (Wispr Flow's). Every newsletter sets its own limits, so confirm them with the writer before drafting.

Writing the placement

• Write 2–3 variants per placement so you and the writer have options and something to compare against later.
• One angle and one call to action. A primary slot has room for one argument and one link.
• Match the list. A developer newsletter gets the developer angle and proof, even if your homepage leads with something else.
• Use only claims you can back. Keep a list of approved claims and proof points, and draw from it.
• Fit the newsletter's voice. Many writers rewrite sponsor copy in their own voice, and those versions usually do better. Send talking points, the required lines (offer, link, disclosure), and permission to rework the rest.
• Disclose. The placement needs a clear "Sponsored" or "Presented by" label; see the disclosure section of this skill.

For the copy itself, see copywriting. For tightening a draft, see copy-editing.

One file and one tracked link per placement

• One file per send date and placement, for example sponsorships/{partner}/2026-04-17-{publication}-primary.md. Never combine two send dates in one file. Each placement needs its own link, its own checks, and its own record of who approved it.
• Record the angle in that file. That's where the read-past-results step gets it later.
• One tracked link per placement, even for two sends in the same week. A short link makes the copy cleaner and lets you change the destination after the issue ships. Build the UTMs with the newsletter pattern in analytics (UTM Patterns by Partner Type): the campaign rolls up the month, and the content value names the placement and date.
• Add a promo code when the newsletter allows it. It catches readers who type the URL instead of clicking.

Reporting

• Per placement: clicks, signups, activated or paying users, revenue, cost per click, and cost per signup.
• Check that the clicks are people. B2B lists can pick up clicks from corporate email-security scanners that follow every link. If clicks far outnumber analytics sessions from that link, discount them.
• Add a "How did you hear about us?" question to signup. Newsletter readers often search for you later instead of clicking, and that shows up as branded search or direct (see attribution).
• Decide after 2–3 placements per newsletter: renew, change the angle or slot, or drop it. One bad send is too little data to judge, unless it never went out.
• Feed the results back. Add each placement's angle and result to the table above, so the next brief starts from it.
